Abstract
Abstract The post‐polymerization modification of selenophene‐containing (co)polymers is presented based on the electrochemical polymer reaction (ECPR). Selenophene‐ or thiophene‐containing (co)polymers, which are known to be promising materials in optoelectronic devices, were synthesized through Kumada catalyst transfer polymerization to give their homopolymers and block‐ or statistical copolymers with various side chains. Each of the series of polymers was subjected to post‐modification through the ECPR, and the reaction efficiencies were systematically compared. Selenophene‐containing polymers were successfully modified with better ECPR reaction efficiencies than their thiophene analogues. Moreover, the dramatic inhibiting effect of a branched side chain on the ECPR was observed and rationalized, which was very unexpected. Based on the basic tendency observed here, we have finally demonstrated the selective modification of a single segment of a rod−rod block copolymer for the first time.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
